Abstract
A system may include a power converter configured to convert a source voltage from a power source to an output voltage at an output capacitor at an output of the power converter, a dual-mode power converter electrically coupled to the power converter, the dual-mode power converter having a plurality of switches and a power inductor, an energy storage element electrically coupled to the dual-mode power converter, and control circuity configured to, when the output voltage is below a threshold voltage magnitude, control the plurality of switches to operate the dual-mode power converter as a buck converter in order to transfer energy from the energy storage element to the output capacitor via an electrical current through the power inductor.
